I have a MultiMix16 FireWire going into the FireWire port on the back of an Audigy 2 ZS, which is a 1394a port. I am using Sonar 4 Producer edition with it. Running Win XP Pro, SP2, always updated with most current patches.
I’ve had this unit since January, and read all the posts here ~before~ I bought the unit, so the first thing I did was get the new drivers and firmware installed.
No problem getting the unit up and running with the ASIO drivers, and I’ve been using it non-stop since. Along the way I’ve had issues with the occasional dropouts in playback (interesting, it will still record without a hiccup even though the mix playback stops) and driver tweaking, but I’ve found a few things make a big difference on my system:
1) Before I start a session, I will shut the PC completely off and re-start it. (This PC is shared, and I’ve noticed after a some FPS games have been played ~something~ changes in the system.)
2) Disable virus scanner. The scanner hooks into the OS and slows it down, and if you are unfortunate enough to need the “On Access Scan†set (meaning those of us with teenager girls who live their lives on AIM and seem to click on every piece of crap that pops up on their screen) it will look at your files whenever they are touched. Sonar is constantly modifying audio files. (It has to.)
3) Shut down every program in the tray area, 4) <Ctrl><Alt><Del>, click on “Processes†and shut down all unneeded tasks. For me, this is OpWare (for my scanner), iTunesHelper (I removed it from startup, but it returns every time there is an update from iTunes), McAfee updater service, and a few other programming tools I usually have running on my machine. It is good to know what is necessary, and what is fluff. Go to:

5) Turn on the MultiMix and wait for the <DING!> from Windows telling me it has loaded the driver and is ready to go. 6) Start SONAR So far, my system has been pretty stable. I do still occasionally get a minor dropout (on the order of a few milliseconds) on during playback, but recording (even during a dropout) is flawless, and mixdowns are flawless.
Hope this helps people just getting started with this!
